Deck jump

The sketch below shows a positive deck jump (English sheer ): the stern and bow are higher than the center of the ship

The deck jump (sometimes also deck jump ) describes the curved course of the upper deck of ships and yachts - in the longitudinal direction of the ship, viewed from the side .

To increase seaworthiness , the upper deck rises partly towards the bow or towards the stern (the freeboard is then smaller amidships than at the bow or stern). In this case, one speaks of a positive cover jump. In the opposite case (if the deck is higher amidships than at the bow or stern) it is referred to as a negative deck jump.

A strong deck jump is an expression of classic lines, especially in sailing yacht construction.
